I would resolve this issue but there is few information to do it.
I think that no boundary in header,C#Mail cannot parse mail data correctly.
Please send me the entire mail text and I would be able to resolve this issue exactly.

Thank you for sending me a mail.
I check your mail and found out that the mail is invalid format (RFC822).

One thing I notice is that the mail is include the word "X509Certificate".
My C#Mail library only support pop,a-pop, I didn't check some of secure mail protocol.

I'm not certain what I notice is correct or not,the only thing it is true is that this mail does not valid RFC822 format.
